Passenger window switches don't work?

[unioncreek]

The passenger windows on my 95 Aurora don't go down when you use there switch. I can make them go down with the controls at the drivers door. I had the drivers door apart and cleaned it good with electronics cleaner, but that didn't help. Took one of the rear one's off and cleaned it,but nothing. Anyone have any suggestions about where to look for the problem?

Thanks,
